H A R R O SPECIFICATION forming part of Letters Patent No. 387,202, dated August '7, 1388.

Application filed December 152, 1887. Serial No. 257,692. (No model.)

To @ZZ whom it may concern:

Be it known that I, J nains H. BARLEY, a citizen of the United States of America, residing at Sedalia, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in Hariows, ol' which the following is a specification.

My invention relates to certain improvements in iield dragharrows; and it consists, first, in the combination of a harrow -tootli having its upper end bent passing horizontally through an opening located in the upper portion ofthe metal tooth bar or rail forming the upper supports for said tooth, the outer bent end thereof having an integral self-retaining head bent or formed thereon, and the lower support for said tooth detaehably connected to the lower portion of said bar or rail, to which the upper end of said tooth is attached and supported in position; second, in a harrowtooth bar or rail having a series of upper and lower tooth supports, in combination with the harrow -teeth bent at their upper ends passing horizontally through perforations formed through the side of thenpper portion of said bar or rail forming the upper supports for the teeth, and having inA tegral self-retaining heads bent or formed on the outer ends ofthe upper bent arms thereof, whereby said teeth are held in their respective places, the lower supports for the teeth de; tachably connected to the lower part of said bar or rail, to which the upper ends of said teet-h are attached; third, in the combination of a twopart metal harrow-tooth bar or rail detaehabl y connected each one with the other, having tootli-openings at its upper portion, the upper ends ofthe harrow-teeth bent pass ing through said openings, the upper bent ends of said teeth having self-retaining heads formed on their outer ends, the lower supports for the teeth detachably connected with the loottorn part ot' said bar or rail; fourth,in a two'part metal barrow-tooth bar or rail having pcrfora tions in its upper portion, the upper ends of the barrow-teeth bent passing through said perforations, the outer bent ends of said teeth having integral tooth-retaining heads formed on them, and an angle or l. shaped detachabl yconnected base having perforations through its lower horizontal projecting portion which receives and forms the lower support for the teeth; iii'th, in a two-part metal barrow-tooth bar or rail having perforatious in the side of its upper part, and the harrow teeth bent at their upper ends passing through said perforations, said teeth having integral selfretaining heads formed on the outer ends of the ripper bent arms thereof that project through said bar or rail, and an angle or L. shaped base having its vertical portion detachably connected with that part of said bar or rail which supports the upper ends of the teeth, and the lat-eral projecting Iiange of said base, having oblong pert'orations adapted to receive and forni the lower supports for the selfadjusting teeth to stand at diierent angles.

The object of this invention is to furnish barrow-tooth bars or rails having upper and lower tooth-supports detaehably connected therewith, and the harrow-teeth, bent at their upper ends, inserted in said supports, having integral heads formed on the outer bent ends thereof, whereby said teeth are held in their respective places without the intervention of nuts, bolts, clamps, keys, pins, rivets, or devices of any kind being applied to the upper ends of said teeth.

All the advantages gained by the construction of my improved barrow-tooth and rail above referred to I attain by the mechanism as herein described, and illustrated in the accompanying, drawings lforming part of this specification.

Referring to the drawings, Figures l, 2, 3, and 4 are side elevations of my improved harrow-tooth bar or rail having the usual number of teeth attached in their respective'places and supported at different angles. Figs. 5, 6, 7, 8, 10, and 13 are views of tooth-rail :in vertical cross-section with teeth attached, showing slight variations in the manner of arranging the upper and lower supports for said teeth. Fig. ll is a tooth-supporting clamp. Figs. 9 and v12 are top edge views of sections of tooth bar or rail, showing the lower tooth-supports further varied in form. Fig. 14 is aside view of a section of tooth-rail, showing the opening forming the upper tooth-supports varied in form of construction. Figs. l5, 16, and 17 are views of the harrow-teeth in side elevation, showing the upper end bent and having an inv IOO tegral self-retaining head formed on the outer bent end thereof, which is slightly Varied in the manner in which said head is formed.

In the drawings, A represents the tooth bar or rail of which the harrow-sections are formed, and B are the teeth.

In the embodiment of this invention I cmploy metal bars, which form the toothrails A proper. Through the side of the upper portion of said bar ascries of openings or perforations, A, are formed, at suitable distances apart, which receive and support the upper ends of the teeth. The lower tooth-supports maybe formed by the use of an angle 0r L shaped metal base having its vertical iiange A2 detachably connected with the lower part of the bar A by bolts or rivets, or any other suitable means may be employed to hold the two parts together. Through the lower laterally-projecting flange, A', forming said base, aseries of perforations, Ai", relative in number to the perforations A in the side, are formed, which receive and support the lower portion of said teeth. The upper endsof the teeth are then bent or formed at or near a right angle, forming the horizontal portion B. The outer end olsaid bentportion is then either bent pointing downward, upward, or sidewise, or an oval or button shaped head, B2, is formed integral therewith, as shown in the drawings, Figs. 15, 16, and 17. The teeth are then inserted through the perforations A4 with their lower point ends turned downward to stand as shown in the drawings, Fig. 6. The points of the teeth are then inserted through the perforations A3 in the base-flange A', which is passed up over the teeth, and the flange A2 of said angle or L shaped base is attached to the lower portion of the bar A, thus forming the tooth bar or rail complete, as shown in the drawings, Figs. 1, 2, 5, and 7.

Vhen harrows are wanted having the teeth attached rigidly to the rails, the perforations A3 in the base-ange A' are made the size of the teeth to be used,as shown in the drawings, Fig.2; and when self adj usting teeth are preferred the perforations A3 in the base-flange are made oblong, as shown in the drawings, Fig. 1, allowing the teeth having a free horizontal movement on their upper bent pivot-arms, B. The shoulders C C, at alternate ends of said perforations,support the teeth in a vertical position when the barrow is drawn in one direction and in an inclined position when the motion of the barrow is reversed to the opposite direction, as shown in the solid and dotted line drawings, Fig. 1.

The oblong perforations A3, above referred to,rnay be formed parallel with the rail or base ange A', or they may be formed either angular or flaring rearwardly, for the purpose of permitting the lower ends ot' the teeth falling out into a line of travel when working in a slanting position. l

Ido not restrict myselfl to using my improved barrow-tooth exclusively in connection with a har or rail having an angle or L shaped detachably-connected base,provided with perforations A3, for supporting the lower portions of the teeth, as eye or loop shaped bolts or other suitable metal fastenings may be detachably connected to the bottom portion of said toothbars, forming the respective lower supports foreach tooth, as shown in the drawings, Figs. 3, 4, 8, 9, 10, 11, 12, and 14. In this instance the teeth may be supported on the rails rigidly by forming the openings in their lower supports the size of the teeth used, as shown in the drawings, Figs. 1-, 10, 12, and 14, or said openings may be formed oblong with the rails, allowing the teeth having a horizontal movement on their pivots B' to stand at different angles, as shown in the drawings, Figs. 3, 8, and 9. Itis therefore obvious that the special manner of constructing these lower tooth-snpports may be further varied in form. v

In the drawings, Figs. 4, 10, and 11, an eye or loop shaped screw-bolt, D, is employed having one or more tangs, D', passing through perforations i'n the lower portion of said rail. These loop-supports may he so formed with sui'ricient longitudinal space between their two arms or tangs D', adapted to support the teeth either in a vertical or inclined position, as shown in the drawings, Figs. 3, 8, and 9, before referred to. One end of the tooth-supporting arm or tang D' may be bent, forming a hook-shaped end, D2, passing through the rail A, while the other arm thereof may pass through said rail, having a thread and nut on its point end D, or said last-mentioned arm or tang may he formed into an eye, D, to admit of a bolt or rivet, D5, passing through said eye and rail, as shown inthe drawings, Fig. 9; or, in lieu of said loop, having tangs D' D', as shown and described, the lower tooth-supports may be made of malleable or wrought metal in sections for each tooth, formed in a right angle or L. shape, D, having openings through theirlower horizontal portion, A', to receive and support the lower ends ot' said teeth, the vertical part AL thereof being detachably connected to the lower portion of said bar or rail A by bolts or rivets, as shown in the drawings, Figs. 9, 10, and 12, and also at end teeth of rails in the drawings, Figs. 3 and 4.

Either one or both of the upper and lower tooth-supports may be detachably connected to the vertical portion of said tooth baror rail, as shown in the drawings,Figs. 13 and 14,where a loar or strip of metal, A5, may be used, having perforations therein for the upper end of the teeth to enter, or corresponding notches may be formed or rounded out in the top edge of the bar A,and in the lower edge ofthe bar A5, so as to forni openings A the size ofthe teeth when the two parts are connect-ed in place, each one with the other, by bolts or rivets, as shown at drawings, Fig. 13.

Referring again to my improved tooth having integral self-retaining heads B2 formed in the manner shown, either one is equally well IOO adapted to be used in connection with either ofthe bars or rails, as shown in the drawings, Figs. 1, 2, 3, 4, and la.

I ani aware that prior to my invention metal harrow tooth supporting beams have been used having a lateral projecting tiange formed integral with its vertical portion, forming said beam of a single piece of an angle or l... shape metal.

Having fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-
